Rancho RS9000XL 0-2″ Lift Shocks for 1973-1986 Chevy K-20 4WD

Part Number: RS999151

Summary: The Rancho RS9000XL series provides the ultimate in ride control for the classic Chevy K-20 4WD and GMC Suburban. Featuring a 9-position manual adjustment knob, these shocks allow you to instantly tune your suspension for daily commuting, heavy towing, or off-road excursions. Engineered to accommodate up to a 2-inch lift, this set delivers a customized damping profile that eliminates the “one size fits all” compromise of standard shocks.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure the driver can transition from a soft street ride to firm control for towing.
• Nitrogen Gas Pressurization: High-pressure gas charging provides a reduction in aeration and foaming to ensure consistent performance during rapid cycling.
• Large Shock Body: A heavy-duty 2.75-in. diameter body provides increased fluid capacity to ensure cooler operating temperatures during demanding use.
• Polyurethane Bushings: High-density polyurethane material provides enhanced durability and reduced deflection to ensure precise steering response.
